POUR-ING DEVICE FOB HOT-METAL CONTAINERS.

vApplication 1ed March 30, 1923. Serial No. 628,873.

To all whom t may concern: i

Be it known that I, JOHN D. PUGH, a citizen of the United States, and residing at Mount 'VVashingtom Baltimore, Maryland, have invented certain new and useful lmprovements in Pouring Devices for Hot- Metal Containers, of which the following is a specification;

This invention relates to pouring devices for hot metal containers.

In the manufacture of iron and steel, containers or ladles adapted to hold'inolten metal have long been -in use for transferring metal from place to place, in which case the containers are mounted on wheel trucks, or for receiving the molten metal from the furnace and pouring into various smaller receptacles, in which case the containers may be stationary. A thoroughly efficient container of this character is disclosed in Patent No. 1,251,282 issued to me December 25, 1917. This container is of the closed body type, that is, the metal held therein is completely enclosed by the walls of the container except for pouring openings in the top, which openings may be closed by lids, if desired. Other types of ladles or containers have been used but such containers have not been of the closed body type, the upper surface of the metal being exposed to the air, allowing heat to rapidly escape from the body ofthe metal so that it may remain in the container in a molten condition for only arelatively short length of time The closed body container invented by me may be either mounted on a car truck or upon a stationary frameV inv any suitable mannerbut is generally provided wit-h two pairs of aligned trunnions about either set of which the container body may be tilted in the frame bearings in which the trunnions rest, to discharge the metal through either of the two top pouring spouts into a receptacle or trough to one side of the same.

It is found desirable, under some' circumstances, to pour the hot.v metal into a trough located to one side ofthe containerA at a relatively highv level as compared with the position of the container when atrest. `In Vmany lcases pig casting machines, or other devices, have their receiving ends placed above the track level supporting the hot ATENTOFFICE.. y

metal car. `This is generally done to avoid placing the machinery in a pit, which is diflicult to drain, or objectionable for other reasons.` Wherever for any reason therefore, Vthe receiving trough is high relatively to the track,-it is necessary to have the car spout pour in a high position.

It has heretofore been suggested that the contents of hot metal containers of the open top type may be emptied into a trough positioned at a relatively nhigh level by providing a stand positioned adjacent the container and in position toV support the same, the container being first tilted on the main container trunnions until the stand vis enf gagedlby an auxiliary trunnion or bearing on the container and is then further tilted about the bearing or trunnion on the upper the -lipof the container spout, the said lip y does not travel laterally very far over the edge of the receiving trough, and the flowing metal tends to pour more :nearly in one spot in the trough and to wear away thesame. i

There are two principal objects of the present invention, the first being tol provide a flexible pouring device tofcooperate with a container of either the open or closed body type by means of which the contents of the container may be discharged at a relatively,

high levelas compared with the position of the container when at rest, and the second' object being toy provide a pouring device which is particularly adapted to advance `the spout laterally over the edge of the receiving trough.

1While I have illustrated in the drawingsand will describe in detail below, the in vention especially adapted to assist in* the tilting and emptying of acontainer of ex' actly circular cross section, itiwill befga'pparentthat the side support mayf be used with containers of other cross sectional formations, and is not limited in this respect, the forms of the inventionillustrated in the drawings. being given by Way olf example only. V In the drawings: Y

Referring first to the form of the 'invention` illustrated in Figures l', 2, 3 and:.(i',..it will be Vseen that. the .pouring lstands 'there illustrated are `particularly adapted to-coopcrate. with a closed body container which is mounted -ion ,a :car truck. rEhel container body l0 is provided with twor'sets'o': alignedV trunnions 1l, Which rest in bearings 12 sup.- ported upon and extending '.transsiersely et the car sills 13. These sills may be straight,V as shown in F i-gurelorv of 'the idroip "traine The car truck. isxin'ouirted on, rails. 14. and the base 15 .is located beside .the

track, .as shown in .Figure .2,4 to support the pouring stand S. The ,stand S. be formed' i'n various .Ways ybutfas shown comprises .spaced uprights. 16 braced, `and toy .the 'faces of which.y are secured` bearing blocks 17.

the. upper. ends of these chains 'beingad'fjustably secured bybolts 19, to a cross piece 2O mounted; atV the', upper end, .of the 'stand and having their lower ends secured to a isa similar View th-rough. a: stand.

. mayv suitably Y These bloc-les arey provided with bearing surfaceslif4 -arrair-gedV oth er suspended member or socket 21. This member has a groove 22 therein Which is preferably undercut as shown in y Figure 2, Wal-ls of the socketj flaring outward as shown in Figure 3, so that they may be said to be bell mouthed. The member 21 caff be adjusted vertically through limited distances .by means of the screw` bolts 19 and horizontally bymeans of shims or screw bolts .Nqextending through nuts N secured to the stand. p

The groove 22 of 3member is adapite'd; to receive a roundeddrib. lor lug 23 rigidly and strongly secured to the Wall of the container 10 and substantially in -thegsameplane as the trunnions 1L This lug has tapered or pointedends. 241: Which as shown inl Figure 2, a. sling or cable troni. an` lover-head cranel or power apparatusris. attached to the containerV body at 2,5 and.

a vertical up-Ward pull exerted thereon. TheA trunnions 1,1 immediately leave their socket bearings and the lentire container commences to rotateI yabout .its .right Ahand point of suspension, ,that is, the lug 23 tates in groove 2 2. This rotation continues until the container body reachesvthe ,position indicated yin dot and dash linesiFiguiie 2) Where the rounded surface thereof' iirst makes contact. withvgthe bearing surface 1.7 of the stand.` Further lifting by therane or hoist causes ythe ycontainer to roll up Wardly along these` bearing surfaces .and this movement may Abe l.continued until. the container 'has rotated .approximately through l" into the dotted line` position. (Figure 2).(` the axis of the `bottom pour-f ing spout 10 being then-horizontal so vthat no` metal, can yremain in thev container. y

A trough. 27 receives; the. molten. metal and conveys it to the casting head or `Whereever needed. After vthecentainer `1lhas .been

emptied it may be loweredvruntilirtlie trun-v iiion-s 11 are againseated in .their bearings.- 'llhe car may be then dra-Wn alo-ngfthe track by,v an. engine;and=,theflug1 23 yvilljautomatically disengage itselffgfrom the' suspended"` and forthfflow' of the hot rmetal:asis rre-V quently the Vcase yivvheretlie container ro?.l

tates lirst on its "trunnions and then makes contact with the pouring stand. It will be further seen thatall practical variations in track alignment are provided for in the bell mouth ends of socket, 21,7whichv has vertical and horizontal adjustment, and tapering ends of lug 23, so 'that tnese'members can always be made to register with certainty and the 4iexibility before mentioned is attained. The lip of the container spout also has considerable lateral movement inpouring.y j j As can be seen inl Figure 6, the member 21 has its rear corners cut 'away' at 30 and lugs 31 are provided to fit in the recesses thus formed. These lugs lock the member 21 against longitudinal horizontal movement as the car moves into pouring position and lug 23 is entering the slot 22.

In Figure 4 the stand S is shown to have a curved bearing surface 40 so that the container rolls laterally as well as upwardly and the pouring spout 102 is advanced laterally to a considerable distance which is advantageous in many instances for reasons before indicated. In this form of the invention the same socket 22 andlug 23 may be used, but a modification of the same is here shown in which the suspended member 21 is hook shaped and the lug 23 secured to the container is substantially in the form of an oppositely turned hook. The outer ends of member 21. flare outwardly and the ends of lug 23 taper inwardly for the same reasons set forth in connection with members 21 and 23 of the form shown in VFigure 2. The member 21 is pivoted at 41 tol a flexible member 18 the effective length of which may be adjusted by vmeans of a hand wheel 42. As the container is raised in the pouring operationl the initial turning movement will be about the pivot 41 but -as soon as the wall of the' container strikes the curved bearing surface 40 further movement will be in the nature of a rolling movement on this surface. The suspended member 21is provided with a rearwardly ex,- tending lug 43 which extends into a recess 44 in the face of the stand. The member 21 is thereby locked against longitudinal, horizontal movement as the container is being moved into pouring position.

In Figure 5 the container 101L is shown to be mounted upon stationary supporting rollers 45. The pouring stand S2 is in general similar to that shown in Figure 4 with the exception that the suspended member 212 is similar to that illustrated in Figure 2 and cooperates with a lug 232 similar to lug 23 shown in that figure. The mode ofy operation is exactly the same as before.

In Figure 7 a section of a further modified form of stand is illustrated. In this instance there are two short suspended members or sockets 46 instead of a single continuous member and two separate lugs 4'( secured to the containertol cooperate therewith. Other modified forms of interengagmay be designed and employed to suit conditions.

In Figure9 a hotmetal car of common type is shown which is equipped with a rib for engagement with my improved high pouring stand. Shims,indicated at 50, are

provided for the purpose of adjusting the socket 51 laterallyvin case the tracks are not laid in theY samev true horizontal plane.V

Adjusting bolts may be employed for this purpose instead of shims, if desired.
